  • Vapochromic materials and methods of making and using same
    Patent number: 8999718
    Abstract: A vapochromic gold-copper complex [AuL2(Cu(Y)n)2](X)3 exhibiting luminescence is provided, where L is an N-heterocyclic carbene; Y is a heteroatom-containing ligand; X is an anion, and n is an integer having a value of 1 or 2, and solvates thereof. A reaction of [AuL2(Cu(Y)n)2](X)3 with water vapor or an organic compound vapor, for example, affords a modified complex that yields a change in luminescence color under UV excitation. These tricationic vapochromic materials exhibit large changes in the emission through ligand substitution reactions between the solid complex and vapors, which permit use in luminescent vapochromic sensors.
    Type: Grant

    Date of Patent: April 7, 2015
    Assignee: Board of Regents of the Nevada System of Higher Education, on behalf of the University of Nevada, Reno
